Fix exception on ARM32 with VS2022 when Print() is invoked 

On ARM32 only, it appears that whenever Visual Studio inlines the FloatToString()
call (which it does for Release builds), the resulting executable produces an
"Undefined OpCode Exception" on Print() invocation, regardless of whether there
is an actual float to string conversion occurring there.

To work around this, add an explicit clause to prevent inlining, and do so on all
platform just in case.
